Answer 1

he table shows the outputs y for different inputs x:


Input
(x) 2 4 6 8
Output
(y) 1 2 3 4


Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 3x – 10. Which relation has a greater value when x = 8? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)

Answer 2

Yes they do represent a function because it is y= 1/2x

Answer 3

They do because the x values or the domain doesn't repeat?

Answer 4

B) If we plug in 8 to y=1/2x then we get 4, if we plug it in to 3x-10 we get 14 so ....

Answer 5

Yes also because it does not repeat

Answer 6

Alright

Answer 7

so the data in the equation has more value?

Answer 8

for B yes the 3x-10 has greater value

Answer 9

C) if y=80 and the starting equation was y=1/2x Then we have to multiply 80 by 2 and we get x= 160

Answer 10

Sweet, thank you!!
